What causes climate change

    What causes climate change

  • 1 Burning of fossil fuels

    When fossil fuels are burned, carbon dioxide is emitted. Carbon dioxide accumulation makes the layer of greenhouse gas surrounding Earth thicker and thus the planet becomes warmer.

  • 2 Deforestation

    Trees help in maintaining the gas balance of the atmosphere as they absorb carbon dioxide. When trees are cut down more CO2 remains in the atmosphere, thus causing the planet's temperature to rise.

  • 3 Using commercial and organic fertilizers

    The use of commercial and organic fertilizers results in the emission of Nitrous Oxide, a greenhouse gas which has the same effect of CO2 on the planet's temperature.

  • 4 Decomposition of wastes in landfills

    The process of decomposition of wastes in landfills results in the production of greenhouse gases such as Methane and Nitrous Oxide. See the effects of climate change.

  • 5 Chlorofluorocarbons (CFCs)

    The production of Chlorofluorocarbons (CFCs), compounds used in many industries, contributes to the rising temperature of the planet.

  • 6 Solar irradiance

    According to Nasa, the current climate change has nothing to do with the change in energy the sun provides us with, as the sun's energy has been relatively stable since 1750. However, previous climate changes were sometimes caused by the change in the sun's energy.

  • 7 Changes in volcanic activities

    The change in volcanic activities is one of the causes of climate change. However, man-made activities are responsible for the greatest share of the problem.

  • 8 Agriculture practices

    Many of the agriculture practices humans do result in the emission of greenhouse gases, such as No2, that contribute to the problem even more.

  • 9 Changes in Earth’s orbit

    The earth revolves around the sun in an elliptical orbit. However, the shape of the ellipse can change from time to time and this can contribute to climate change, as it affects the amount of energy reaching earth directly.

  • 10 Changes in Earth’s axis of rotation

    The earth rotates around a slightly tilted axis. The angle of that axis changes within a range of 22.1 to 24.5 over the years. When the angle increases, summer becomes warmer and winter becomes colder.

  • 11 Change in ocean currents

    Ocean currents carry heat from one place to another as they travel. Small changes in ocean currents can result in big changes in energy distribution.

  • 12 Movement of tectonic plates

    As the tectonic plates (the plates that carry earth's continents) move, some areas might experience changes in their weather as its position on Earth changes.
